Application led February 3, 1913. Serial No. 745,981.

To 'all whom it may concern:

Be it known thatwe, BYRON BLISS WELLS and LESLIE WALTER LAPP, citizens of the United States, residing at Columbus, in the county of Franklin, State ofY Ohio, have invented certain new and useful Tmprovements in Controlling Mechanisms for Automobiles.

The invention relates to the mechanism used in connection with the clutch and the f transmission mechanism, and has for its obof an lautomobile provided with steering mechanism and motor; also. clutch mechanism for releasing the motor from the driving mechanism of the machine. shows the gear box, in which is contained a Tt also l series of gears for changing the speed ratio between the rear axle and the motor Aalso showing connecting means between the' rear axle and the gear box, and the diHereV-ntial -mechanism All of these parts as enumerated are devices common to the art, and 1n the main there is no deviation from'their` regular construction.

Fig. II is a top view of ing the top portion removed and also a top view of the mechanism which is used to shift the gears as desired. It also. shows the.

Fig. XI is a view ofthe worm and gear of the steering mechanism. In Fig. 1,'1, 1, are the front wheels pivoted to'an axle 2 which supports the front portion of the frames17 and 18; 3 and 4 are v i arms connected to the spindles 5 and 6; 7 ,is

a rod attached to the ends of the arms 3 and 4, and holds the wheels 1 in a parallel posi-d a shaft 9 suitable worm and gear 1 0 and 11, whlch in turn operates through a lever 12 and a rod 13, which is in turn pivoted to `an4 ,tion The steering wheel 8- operates through f arm 14 integral with the arm 4: 15 is an internal combustion motor of a kind whichis commonly used in the art, which is supplied with a source of electrical energy 16 for.

igniting gases after they have been compressed in the various cylinders. i

Themotor asshown in this drawing 1s of the usual four cycle type. The style of l motor has no part in the invention as either gas, steam, electric or any other source of power is lsuitable .to the invention.

50 is'the balance wheel of the motor having a'frearwardly extending portion 151, which is constructed to receive the clutch mechanism; 52 'is a. rod extending between the-frames 17 and 18 of the machine and f carrying 7the foot pedal 81 and the brake the gear box haw'I pedal 54. This rod 52 also supports bars 55 and 56. These bars 55 and 56 are fastened at clutch mechanism for disengaging the motor from the driving mechanism.

vrrnmediately in front of the rod 52 and supported by the bars 55 and 56 is a'rodl 53, which carries mechanism for releaslng the clutch.v This mechanism will be. referred to later in the description. n

Immediately in front of the rod 53 1s a rod60 which carries mechanism for operating the gears contained in the gear box 57'.

Therods y62 and 154 actin conjunction with the mechanism which is suspended on rod 60 -to shift the gears contained in the box 57..

, All of thesevparts will be referred to later y I Figs. vn, VIII and Ix aretiews of theindicator and foot-plate of the pedal.

Fig. X is a diagrammatical view of the `Vguide plate for preventing the setting of thefoot plate'being changed during the operation of the foot pedal,

and full discussion of them giyen.

-Th'e shaft 68 is ,connected by suitable mechanism to the clutch and extends lnto the gear box 57. The shaft 69 extends from the.v

reariend ofthe I'gear box 57 and operates thepropellershaft 71 through a' universal, joint 70. 4. y lropeller shaft 71 has attachedto its rear end abeveledpinion 7 2 which works in con; 1

junction with a beveled gear 73. This bevel gear is connected .to the shafts 74 and 75 through suitable diiferentialmechanism 76.

4'lhis differential mechanism is commonly liznownin.` the art and it is not necessary to describe its details.

The shafts 74 and 75 are fastened to the wheels 77 and 78. It is evident that the power 'generated by the motor 15 will be l transmitted through the clutch mechanism wheels 77 and 78.

tothe shaft 68, which will in turn transmit it'through the. gears in the box 5 7 to the' shaft .69'. The shaft 69 in turn operating through the universal joint 70 drives the shaft 71, which in turn causes the shafts 74 vand 75 to rotate through" the action of the pinion 72 and the gear 73. The shafts 74 and 75 in turn transmit the power to the The mechanismas 'above described is of the ordinary type which is commonly used in motor propelled vehicles.

In Figs. 3 and 6, 58 is a frame suspended on the rod 52 which extends upward and at its top has a forwardly projecting part' 79 which extends through an opening in the- 82 is attached to a rod 83 extending through the part 79 of the frame 58. Near the top portion and at the sides of plate 82 are rearwardly projecting parts 8,3% At: the lower..l

portionof the plate 82l are rearwardly projecting portions 84. These parts 84 have elongated holes 85 and screws 86v by which they are attached to the plate 82. *These rearwardly projecting parts 84 on the plate 82 are so arranged that they'can be adjusted to lit the shoe ofthe driver.

to right 'orto left the pointer 83 will be brought to indicate either ofthe positions 5d R-1-N-3-2. A s the'plate is turned'by the action of the foot the roundedportion 83a at the `bottom of'the plate will engage ,in

The forward portion of the part 79 `is a sleeve 88 through which the rod 83b passes.

This sleeve is held in position by a set screw 89. At the rear end of the rod 83b is a sleeve 90 which is fastened Arigidly to the rod 83b by a pin 91. About the rod 83 and between the sleeves 88 and 90 is a coiled spring 92.

Itis obvious that the action of this'spring willbe such that the projection 83 ofthe plate 81 will be held firmly in any one of the notches 2f 3 N '1 R,"in which it may be placed. i

The plate 82 is attached to rod 83 by a The foot is placed on this plate and by turning the foot swivel joint which allows the plate to have a free movement in the other.

At the rear of the rod 83" are attached arms 93 and 94. These arms being fastened to the rod 83b iii such a manner that they turn with it, it is obvious that as the plate 82 is moved to different positions the arms 93 and 94 will be moved to corresponding positions.

Attached to the arm 93 Ais a link 95 which connects to one end of a rod 96 which slides vertically in the frame 58. Fastened rigidly to rod 96 are blocks 97 and 98. Attached to the arm 94 is a link 99, which in turn is connected to the rod 100, which slides in the frame 58. The rod 100 carries blocks 101 and '102.

The rod 103 is carried by the frame 58 and has a coiled spring 104, one end of which acts against a projecting lug 105, and the other endof tlie spring contacts with a pin 106 in the rod 103. The tendency of the spring will be to move the rod toward the shaft 96. A rod 106 is also carried by lugs in the frame 58 and is moved toward the passing fromy one notch to rod 96 by a spring 107.acting against a pin k:110 lies between the blocks 101 and 1.02 and 'the rod 109 is some distance above the block Rods 109 and 110 have springs and 101. If the plate 81 should be moved until the part 83 points to 1, itis obvious that the arm 94 operating through the link 99 will raise rodcarrying blocks 101 and 102 upward and the block 102 will come' to the position 'to engage the rod 110 which will be moved to the right. The block 101 'will then be in close proximity "to the pin 109. It will also be noticed that While the arm 94 is being raised the arm 93 will be lowered, and tha-t owing to the angle at which these arms are placed on the rod 83", thje 'arm 94 will be moving the rod 100 through a maximum distance whilethe arm 93 ,will move the rod 96 through a' minimum distance.

f If the plate 82 be moved one notch farther until it comes to the position R, thearm 94 will be elevated to its highest position and the arm 93 will beA lowered toits lowest p osition and the block 102-will beraised until it passes the rod 110 and the block 101 will be brought into contact with the rod 109. 'I his will project the rod 109 to the right against the pressure of its spring.

The angle of the arms 93 and 94 with the rod 83b is such that while the arm 94 is being turned to its upward position. the block i 97 will not be brought in contact the rod 1061.

If the plate 82 be moved to the position 3,

Ithe arm 94 will be depressed, the arm 93 being elevated, the block 98 will contact with the rod 106g. lf the plate 82 be moved farther to the position 2, the block 98 will pass from beneath the rod'106l and the block 97 will then engage the 'pin 103.

,j While the rod 96 is having its maximum upward Jmovement the rod -100 will be having itsminimum .downward movement and the blocksl 101 and 102 will not contact with pin 110. It is obvious thatv the movement of the plate 82 will project. the pins 103 and 1065-109 and, 110` outward againstthe pressure of their respective springs. The outward j movement of these pins is suliicient to bring rod 62carries a block' 135 which isfastened.

carry adjusting screws 130 and 131. .TheseI screwscontact with the arms 126a 'and 127 and are so arranged as to adjust the arms to any desired position. Extending forward from the frame 125`is an arm 126. Swinging on the rod 60 is a lever having arms Y127g.`

The link 129a connects the arms,

and 1281. 126 and 127% The levers 1271 and 1281gare free to oscillate on the shaft 60. rllhe rod 62` is attached to arm 128a and extends backward and throughthe transmission casel 57. The

to the rod 62 by a set screw 136. Attached to the block 135 is a shifting finger 137.

The mechanism" suspended on the up. wardly` projecting portion of the arm 56` which has just been described, and which consists of mechanism suitable to move the arm W62 backward and forward in the transmission case, is-placed at the right side of theframe 58.. 40n the left side of the frame 58 1s a series of pawls and levers similar to those just described, and which operate the rod 154 in a manner similar to the wayin which the rod 62 is operated.

The arm 12101? the bar -56- carries at its upper portion a frame 140 which is pivoted with the stud 141. l The stud 141 also' carries levers 142 and 143- whichv are pivoted on the stud 141. The frame 140 carries screws 144 against which the outer ends of the levers 142l and 143 rest. These levers 142 and 143 are similar in shape and perform similar functions, as the levers126'? l and v127 previously described.

The frame 140 carriesa'rearwardly projecting portion 145 to the Vforward end of which is pivoted a link.- 146.a This link eX-A tends downward and attaches to the forward end of an arm 147 which extends forward from the hub 148. The arm 147 is attached lto a tube 149 by a set screw 150. The-tube 149 extends over the shaft 60 which has its outer ends pivoted to the-'frames 55 and 56. On the other end of tube 149 is fastened 'I an arm 152 by a set screw153. Attached to the lo-wer end of the arms 152 is a rod 154 which extends rearwardly .and into the transmission case 57. I

The rod 154 carries a block 155, which is held inposition on 'the rod 154 by a set screw 156. This block 155 carries a shifting finger 158.

In the sides of rods 62 and 154 are notches 160, 161, 162, 163,164 and 165. frame of the transmission case are spring pressed plungers 166 and 167, which are con-` '.trolled by'springs 168 and 169, the springs 1n the holding the plungers in -position to engage'` the notches .on the rods 62 and 154.

Attached to the frame 58 atthe polnts 170, 171, 172 and 173 by the pins 174, 175,

176 and-177 are cam plates 180, 181, 182 and 183. rllhese cam platesare held normally in contact with the pins 109, and 110, 103 and 106%, by springs 185, 186, 187 and e188.-

The frames 125 and 140 have forwardly projecting cam portions 190 and 191.

The portion 151 of fly wheel 150 is pr-ovid-v ed with a cone shaped surface 200 which opens outward. A spider 201 has'onits .pe

riphery -a cone surface 202, conforming to the shape of the surface 200.b The face 202 is provided with a leather-or other suitable `material vto cause the spider 201 to engage the surface 202 and to produce ysuflicient friction to cause the spider 201 to rotate in unison withthe fly wheel of the motor. The spider 201 is'held into engagement with the fly wheel by compression springs 204, which lare held in position by the bolts 205, the

j bolts extending through the spider 201 and being anchored-on the flange 206 of a sleeve .207, which is attached to the propeller shaft 68. l The crank shaft 210 of the motor has a threaded portion 211, which carrles ac nut 212. The crank shaft 210 also carries a sleeve 213 which is free to rotate on the crank shaft 210,I but is prevented from slipping'of the shaft by the nut 212. After the sleeve 2.13 has been fastened in its nposition by the nut 212, the sleeve 207 is slip ed over the sleeve 213 and the sleeves 207 an 213 are fastened .together by pins 214-. y

1t will be noticed that by this construction the propeller shaft 68, carrying the sleeve 207, to which is. attached `the sleeve '213 will be free to revolve on the portlon of lthe crank shaft 210 and will be prevented from slipping off this bearing by the nut 13( anism is employed.

j' On the shaft 52 is a circular cam 220 haviuga depressed portion 221 in which a roller 222 normally rests. Pivoted on the shaft 53 is a lever 223. This lever 223 carries at its upperend the roller 222. At the lower portion of the lever 223 are the arms of a yoke, 224 and 225. The arms of this yoke carry pins 226 and 227' which Workin a groove 228 of a sleeve 229 carried by the propeller shaft 68. The sleeve 229 carries rods l230 which are fastened to a flange 231, of the spider 201. The drawings show the clutch mechanism which consists'v of a spider 201 and its con- .nected parts, together with its operating le-- ver 223 in normal position and engaged with the iy wheel of the motor. Y Extending upward from the hub which carries the arms 93 and 94 is an arm' 2401 'i Attached to the footboard 80 by a bolt 242 is a guide 32 22. v l

Vhen the frame 58 is in the normalork retracted position as shown in Fig. IV the arm 240 is free from the guide plate 243 so that it will not interfere with the movementl` of the foot plate 82 when it is desirable to` shift its position to any of the positions R2f N2 32 or 22. If however, the plate 8 2' should be moved to the position R and pushed forward the arm 240 would enter the 1 slot R2 of the plate 243, and so long as the pedal is held in a forward position the arm' 240 being engaged in slot R2 will prevent the plate 82 from being moved to any other position, and likewise if the plate vshouldbe Y moved to the position 1 and pressed forward,

the arm 240 being lengaged in the slot R2, would prevent the plate from being moved from this position. Likewise for the. positions 32 and 22. Thel slots R2 12 32 and 22' hare of the same form and of the same length and each of them.I permits the frame 58 to; be moved to its eXtreme-forward position.

245, the purpose of Whichwill be explained later.

The portion 246 of the slot-N12 is shorter than slots R2 12 32 and 22, and does not permit the frame to move to its extreme forward position when the lever 240 is so placed that it will enter this slot N2. also be explained later.

The gear case 57 contains a series of gears plate 243 having slots LB212122-` This will so arranged that they may be shifted to form various combinations which will give differhe portion the forward end of the transmission case and has attached to it a gear 260. The

propeller shaft. 69 has a bearing in the reary end of transmission case 57 and also a bearing in the pinion 260. The propeller shaft 69 is provided with a'series of keys 264.

Sliding on the propeller shaft 69 is a geary 265, which has key seats 266 corresponding to the keys 264. The gear 265 also has ya hub 267 provided with a flange 268.A A shifting linger 137 enters a groove formed by the flange 268 and the face 269 of the gear 265.

bearings in the crank case 57 is a series of gears '271, 272, 273 and 274. All of these gears are attached firmly to the shaft 270 and all of them rotate in unison with the shaft. Immediately below, and sli htly forwardof the shaft 270 is a shaft 2 5 which rarries a pinion 2.7 6, which engages normally the gear 271.y The gear 276 1s used in connection with the gear 271 to reverse the direction of revolution of the shaft 69, so that it will rotate in a counter direction to the shaft 68.

4'Ilie'gears 272'and 276 are so placed that Mounted ona shaft 270, whose ends have I' the gea'r265 may be moved laterally on the shaft. 69 to engage either of the gears 272 i' and 276.r The gear 274is always in engagement with the gear 260 and it would be ob- ",Vi'ous that the' coultershaft 270 with the gears 271, 272, 273 and 274 will always rece'ive a motion imparted to them whenever vthe gear 260 is in motion. .The shaft 69 carries a second'geaij-28O which has -keyways corresponding to the keys 264 of shaft 69. The gear'280 is free -tomove laterally on l the shaft 69. The gear 280 carries a hub 281 with a ange 282.9' A shifting linger 158 entersl the rece'" formed' b'y-the flange 282 and the face 283 of the* gear 280. The gear 280 has an internal portion'285 which matches the external portion of; the gear 260 so that the gear 280A will slide over the gear 260 and by thls means `the shafts 68 and 69 will be caused to ro# 'tate in unison. The gear 273 is so placed that if the gear -280 i's moved backward engaement will be formed 'between gears 27 3 The slot marked N2.`howe ver,'has a shoulder an 27 4, fortrain of gears 2.60, 274, y272 and y ofthe spider from the surface 200 of the j fiy wheel.. rlhis disengaging of this surface,

from the driving mechanism, allows the motor to run free. k j

.if during the first period ofthecycle the foot plate 82 i's turned` slightly to the left untillever 240 engages the-side 300of the l slot N2, the frame will he stopped when the A lever comes in contact `with the'shoulder 245 in the slot N2. This shoulder 245 will preventthe frame58 from entering the second period ofits cycle sorlongas the arm '240 bears against the side300 of the slot N2.

The frame 58 will go through the first period of the cycle when the lever-240 is placed in either of the slots R2 1232 and 22, buttherer is nothing to prevent. it from entering the l second period.

rllhe second periodA of the' cycle of frame 58 `is employedto move .either :of the gears 265' or 280 to their neutral position, so that the shaft 69 will disconnect entirely from the shaft 68. i Y

These gears are thrown .to neutral position in the following manner: Attached to thev sides of frame 58 are cam plates 180, 181, 182 and 183;; so arranged that their. faces 301, 302,303 and 304 will act fagainst the cam levers 190 andl 191. The". distance hektween. the cam faces 301 and,302, land 303 vand 304 are just greatenough to permit lthe cam levers 190 and 191to pass between them when the frame 58 moves' through thel second period of its first cycle, 1t will benoticed that as these cam plates pass over the cant A levers, the arms 126 and 145 which carry the links 129 and 146 will operate through ntheir respective levers to influence the/rods 62 .and 154 and move them to a position so that the spring pressed plunger 167 will 'v` vengage fireman 161 in. the ma 62 and the -spring pressed plunger 166 will engage .sand 1,67. These plungers do not flock the tions and allow them to be shifted Vbe desired.

the notch 164 in the rod 154.v 'The notches in the rods v62 and 154 are if-shaped to correspond-to the 'shape of` the .plungers 1 66 rods, positively but hold themin their posias may When the` foot plate 82,-is in .the vposition N and the lever A240 isl held against the face 310 ofslot 246, the frame willy be stopipedv at the yend'of the second period of its yrst cycle "and the lever' 240 will travel to thebottorn ofthe slot N2. 1f the foot plate 82 .should be at either of the positions R 1 3 o'r 2, there would be nothing to preinto the third period of its first cycle. 1t is `obvious from the foregoing description, thefirst period. of the first cycle of `the frame 58 serves merely to disengage the motor from the driving mechanism. f

' After passingthrough the first period of vvent the pedal being moved forward and the first cycle theroller 222 .will ride over the larger portion of the cam 220 and the clutch 201 will be held out of engagement with the fly wheel of the motor during the second period of the first cycle. It is obvious that after the clutch is disengaged the cam plates will operate the gears 265 and 280 to return them to their normal positions, andthe frame 58 being held in its normal position by a spring, will be free to return to its normal position after the completion of second period ofJ its first cycle.

-l ,'Jlhird period of the first cycle of the frame 58 will now be described. As has already .been mentioned, the dial on the foot pedal has the letters and numerals R'-1-N- 3- 2, each of these corresponding to the following op' erations: R refers tothe operation necessary to reverse the mechanism, so that the machine will move backward, when the clutch,I

is engaged with the motor,- and -:the footkL pedal has been set toindicate R and has been operated through the first cycleLofV this movementi 1 refers to the first or 10W Speed of the motor, imparting the slowest motion to the rear wheels in relation-'to thefnumber of revolutions thefly lwheel is making.

r1`he letter N, as has already been described,

refers to the neutral position, and' in which Aposition no gea-rs will be thrown into engagement: 3tcorresponds to the highest for-rv 4 ward speed; 2 is the'intermediate or second e' speed, and of course, refers to a speed lower p than third and higher than the first. The l' method o-f shifting the gears in the gear box by the foot pedal will now be described.

e if it is desired to back the machine, the operator Ainserts his 'foot inl the .plate 82 whichfis attachefdto the frame 58. He turns the plate 82 until the pointer 83 registers R;

hethen pushes'the pedal forward, moving theframe 58through the first period of its` .first cycle and disengaging the clutchfroin the-'m torn j The frame 58 -then passes through vth second period of its first cycle.

As the frame 58 starts inthe first period of 4its first cycle the lever 240 will enter the ,slot R2' onthe' guide plate 243; at the same time the rocker arm 94 will lift the rod'100, causing the block 102 to pass a pin 110 'and bringing the block 101 into engagement'with the pin 109, and will hold the pin 109 outwardagainst theltension of its spring and int'ofthepath of the lever 127.

As the frame 58 proceeds through the third .period of its rst cycle, the pin 109 will bear against the face of the lever 127 and will act to move the arm 126 downward and through the link 129a and the arms 127 a and 128a will move the rod 62 rearwardly I i' so that the plunger will enter the slot 160 on the rod 62. At the same time the shifting finger 137 will move backward with the 'the idler gear 27 6.

rod 62'and will lcause the gear 265 to engage The cam 220 which operates the clutch I mechanism throughthe lever'222 will hold the clutch out of engagement with the fly wheel while the frame 58 is moving through the third period of its first cycle. The frame 58 is thenallowed to return' to its normal postion by relieving the pressure of the foot and the frame being carried backward by a s ring. The cam plate 180 'being pivoted at 1 0 and held against the pin 109 EWilll strike the cam lever 190 and pass the the clutch occurs at the latter portion of the second cycle of the frame 58. As the clutch 201 rengages the` fly wheel and is caused to rotate in unison therewith, it will impart a rotary movement to the shaft 68 which hasv fastened to its rear end the gear 260, which engages the gear 274 which is fastened to the shaft 270. Movement is thereby imparted to the shaft 27 0 which in turn imparts like v. movement tothe gear 271 attached to the rear end of the shaft 270. The idler pinion 276 which is in engagement with the gear 271 in turn imparts movement to the gear 265 which causes the shaft 69 to rotate in the counter or reverse direction of thev .Y shaft 68'.

If the foot plate 82 .now be moved to the position 1 and passes through the'first periodof its first" cycle, the clutch 201 will be disengaged 'from the fiy wheel- The lever 240 I l will. have entered-.the vslot l?" of the guide plate 2,43.v f"

55,' third period-.0f its am Cycle when the foot fter the` frame 58 v has completed the plate is set to theV position R, thelever 127 rotating about its center'raises cam lever 190.I This lever is left in this position and remains -there until .the frame 58 is again moved through the second period of its first cycle. In this case the foot plate is set to move-the gears yin the gear box to correspond to the first speed, and before the;

frame 58V can enter its third period of its first cycle, 'the cam levers 190 and 192 must pass between the faces of the cam plates 180, 181, 182 and 183; and as the cam face 190 has been raised so that it will engage theface 301 of cam plate 180, the frame 58 in passing through the second period of its first cycle, will press the cam lever 190 downward, thus rocking the arm 126 upwardand acting through the link 129n and the arms 127a and 128a will move the rod 62 forward and to its neutral position, so that the plunger 167 will again engage the notch 161.

As the rod 62 is moved forward the shifting finger 137 is also moved forward until the gear 267 resumes a neutral position and disengages the pinion A276.

AS the frame 58 enters the third period of its first cycle the rod 100 having been moved to such a distance as to carry the block 102 into engagement with the pin 110 and projecting it outward from the frame 58 so that its point will engage the lever 1266*, and as the frame 58 continues to move through the third period of its first cycle, the'lever 126a Will be moved downward, the arm 126 will be raised and acting through the link 129a and the arms 127l and 128, the rod 62 will bemoved forward until the plunger 167 will enter the slot 162. The shifting finger 137 at the same time being carried forward will bring the gear 265 into engagement with the gear 272. After the frame 58 has completed its first cycle, the pressure of .the foot is relieved and the frame allowed to return to its normal position,- the plate 181 passing the cam lever 190 without moving it.

At the end of its second cycle the roller .222 passes again to the lower portion 121 of the cam 220 and allows the clutch to reen-- gage the fiy wheel of the motor. In doing so the rotary motion is imparted to the shaft 68 and is transmittedthrough the gear 260 to the gear 274, the gear 274 being attached firmly to rod 270 and imparting its movement to gear 272, which is also attached firmly to thesshaft 270. The gear 272 in turn imparts movement to the gear 265, which in turn impart-s movement to the shaft 69 through the splines 264.

It will be noticed that the shaft 69 in this position will rotate in the same direction as the sha-ft 68, but the ratio of the gears 272 and 265 is such that the shaft 69 will rotate much slower than the shaft 68, thus giving the machine its slowest forward movement.

The operator may ynow move the foot plate 82 to the position 2 and by pressing the frame 58 forward which will operate vthrough the cam 220 to release the clutch from the motor as it passes through the first -period of its first cycle. As in the previous operation of the pedal when the pointer 83 was set -to the position 1, the cam 190 is moved downward and ias the frame 58 passes through the second period of its first cycle,

i 50 i greater as. producedin the shaft 68, than is impart-*- i the face 302 of' the cam 181 will engage the camplever 190 and move it to its normal position, which acting through the arms 126, the link 1291, the arms 127a and 128a will move the rod 62 backward until the plunger 167 again engages the neutralnotch 161 and the gear 265 is disengaged from the gear 272, thus throwing-the gears in the gear boX to neutral positions. 1

,As the frame 58enters the third `period of its firstcycle and as the lever 240 is passing through the slot 22, the rocker arm 93 will raise the rod 96 until the block 98 passes the rod 106a andthe block 97 is left in engagement with the pin 103.` This setting of the pin 103 is accomplished at the same time the foot plate 82 is moved to the position 2.

rlihe pin 103 will be projected outward against its spring 104 from the frame 58 until it comes inthe path of the lever 142. The pin bearingagainst the upper face of the lever 142 will move the frame 140, moving its arm '145 downward and acting throughithe-link 146 Aand the arm 147 to rotate the sleeve 149 moving the arm 152, sok as to move the rod 154backward until the plunger 166 enters the notch 163. The shifting Llinger 1 58 will also be carried backward and as it engages the groove on the hubof the gear 280, will move the gear 280 backward at the same time and into engagement with the gear 273. The frame 458 is again allowed to return to its normal position, through its second cycle, the cam plate 183 passing the cam lever 191,'and at the last portion of the second cycle the roller 222 passes to the lower portion 221 of cam 220 allows the clutchagain to rengage the Hy wheel of the motor. The motion of the motor is thereby imparted through the clutch -201 to shaft A68, which is in turn transmitted through the gear 2.60 to the gear 274, which as has been stated before, is fastened rmly to the shaftv 270. The gear 273 being also attached firmly to the shaft 270 will impart movement to the gear 280, which in turn being keyed to the shaft 69 will in turn imp X part the movement to this shaft. The gears 273 andl 2 80 are in such ratio as to'impart a i degree-ofmovementt the shaft 69 .ed to it when the gears 272 and-265`a`re in vengagement, thus giving the shaft 69itsintermediate orsecond forward speed; After the frame 58. has `returned to its'\ normal position, the foot plate 482 can be again moved to position 3. In this position when the 'frame `58- is rocked through theirst period of its first cycle, the clutch, is again disengaged-from the Hy wheel of the motor.

As the frame 58' startstthrough the first period .of its first cycle the lever 240 engaging slot`32, the position of the rod 96 will l 165 be such that the block 98 will engage the rod rIhe gear 280 as previously described,has

either of its live positions, unless the opera- '106% pressing it outward and in the path of the lever 143. As the Vframe 58 passes through the second period of its first cycle the cam plate 303 will engage the cam lever 191 and rock the frame 140 to its normal position and through the link 146 and the sleeve 149 will move the rod 154 until the plunger 166 again engages the neutral slot 164.

. As the frame 58- passes onward and into the third period of its first cycle, the rod 106"1 will engage the lever 143` and through arm 145 will raise the link 146 and through the lever 147 will rock the sleeve 149, moving the lever 152 forward and imparting a like for- 30 ward movement to the rod 154 until the plunger 166 engages the notch 165. The shifting finger 158 will in turn move the gear 280 forward.

an internal gear cut lon its forward side which conforms to the gear 260. The gear 280 will thus slip over the face of the gear 260 and the teeth of internal portion 285 of gear 280 will engage the exterior portion of the ear 260, and as. the gear 280 is keyed tothe s aft 69, the two shafts 68 and 69 will thus become locked together and the same movement that the shaft 68 receives will likewise be imparted to the shaft 69, the two thus rotating in unison. As the frame 58 returns to its normal position, the cam plate 182 passes the cam lever 191 and at the last portion of the second cycle the roller 222 will again pass to the lower portion of cam 220 and the clutch will again engage the fly wheel of the motor and the movement of the motor will thus be imparted to the shaft 68. The .shafts 68 and 69 being'- then locked firmly together, the shaft 69J will'rotate in unison with the shaft 68 and will thus impart the nhighestor third forward speed to the mechanism. l

rlhe movements of the frame 4have been described in their regular order', that is, beginning with the reverse position, then taking up the first or lowest speed, then the second or intermediate speed, and then the thirdor highest speed. llt is obvious, however, that it is not necessary to go through all of these movements as the device is so constructed that when theframe 58 passes through the second periodof its first cycle it always returns to neutral position any gears -frame 58 is rocked through the second period` of its first cycle it may return all parts to neutral position when the foot plate is set` to tor should desire to merely throw out the clutch, in which case he moves the .frame 58 only far enough to accomplish thls result,

or if the lever 240 is in theslot N2 it may be moved to the side 300 of the slot and wlll be 13o v stopped at the shoulder 245. This is to prevent the .possibility of the operator throwing the gears to neutral lposition when he merely desires' to disengage his clutch.- However, if it is only desired to return the gears to normal position heallows the bottom of the slot N2. The setting of, any of the gears is thus prevented after they have been returned to their normal position.`

`VVhenthe frame 58 is in its normal position the foot plate 82 is free,l to be moved'to any of its positions, butgas soon as it enters the first period of its first cycle, the lever 240 must enter one of theslots R2 12 N2 22 82 and after entering these slots the position of the plate 82 cannot be changed until the frame 58 is allowed to return to its normal position. It will also be 'noticed that the frame 58 lmay be allowedto return to its normal p'osi- -setting any gears.
